The long-sleeved black sequined gown got sultry thanks to sheer paneling on the chest and skirt. Paired with statement diamond earrings, the look was classic Hollywood red carpet, and Jones brought with it the type of big smile that proves she knows she’s slaying.

As Siriano told the Hollywood Reporter, “It’s her first nomination, which is so exciting, and she deserves to look fabulous.”

Jones’s fitting took place just after Siriano’s runway show, which explains her screams of joy at seeing the clothes come down the runway. She was seated front row for the show and, as guests put it, “it was almost more exhilarating to watch the comedian watch the show than it was to watch the show itself.”

Jones’s reaction was indeed a joy to behold, but she still wanted the audience to know that she probably wouldn’t have screamed quite so loudly if it hadn’t been her first time at Fashion Week.

“I had never been to [a fashion show] before,” Jones told Yahoo Style. “I don’t think I was appropriate, though. I think I handled it like a baseball game. I was having a real good time.”

Jones celebrated Siriano’s designs and his casting of physically and racially diverse models. “I love plus-size period because that’s realistic, that’s what real women look like. That’s why I love Christian, because he fits all women, all women of color, all women of size,” she said.

As an Emmy nominee, it’s a strong show of support to her friend to wear his dress on the red carpet. Lucky for Jones, she’s not doing Siriano any favors by choosing one of his designs — the dress is simply stunning.

Jones is nominated as Best Supporting Actress in a Comedy Series alongside her SNL castmates Kate McKinnon and Vanessa Bayer. McKinnon took the category last year, at which point Jones, in her own words, “lost her shit” with glee.

Jones better win tonight. If she gets this excited to support her friends, we need to see her when she’s celebrating herself. (UPDATE: Kate McKinnon won again. But Jones no doubt let loose with beautiful glee for her friend and castmate once again.)
